VAR Management to Improve Maximum Loading in Standard IEEE 30 Bus System and Allocation of STATCOM

The demand of electricity has become the parameter of development of a nation. An electricity utility company has to use its existing transmission capacity to feed the ever increasing demand of electricity, due to that the transmission lines has to be operated near its thermal stability limits. Operating the lines near or above thermal stability limits makes system vulnerable to faults more over it also increases the losses in the system. One way to increase the transmission capacity of the system without operating it to its thermal stability limit is to provide reactive power compensation at various locations. Reactive power compensation improves the voltage profile of the system, increase the power transfer in the lines and reduce losses in this project var compensation is processed using newton raphson method and by using the 30 bus system after successful execution of newton raphson load flow technique the amount of real power present in the bus system is modified to its maximum tolerance value. In this project we stressed statcom as the device for the compensation because of its advantages that it has in comparison with the other fact devices
